Brief Summary:
This is a Phase 1 clinical trial evaluating the safety and tolerability of escalating doses of EC0225 in patients with refractory or metastatic tumors who have exhausted standard therapeutic options.

Condition or disease Intervention/treatment Phase
Cancer Drug: EC0225, for Injection (Folic acid desacetylvinblastine hydrazide conjugate) Drug: 99mTC-EC20 (Folic acid-technetium 99m conjugate) Phase 1

Detailed Description:
This is a Phase 1, dose escalation study of EC0225 administered by intravenous bolus (IV) during weeks 1 and 3 of a 4-week cycle to patients with refractory or metastatic cancer who have exhausted standard therapeutic options. EC0225 is a drug that is specifically designed to enter cells via a folate vitamin receptor. Experimental evidence shows that the target receptor is over-expressed in many human cancers. There are no previous human studies of EC0225; however, lab research (research in test tubes or animals) using EC0225 has shown activity against tumors in animals. This activity in animal models suggests that EC0225 may be useful as chemotherapy against human cancers. The primary objective of this study is to determine the safety and maximum tolerated dose of EC0225 given by intravenous bolus. The efficacy of treatment will also be measured.

Intervention Details:
  • Drug: EC0225, for Injection (Folic acid desacetylvinblastine hydrazide conjugate)
    Dose escalation from a starting dose of 0.38mg IV bolus Monday Wednesday and Friday Weeks 1 and 3 of a 4 Week Cycle to the Maximum Tolerated Dose (MTD)
    Other Name: Folic acid desacetylvinblastine hydrazide conjugate
  • Drug: 99mTC-EC20 (Folic acid-technetium 99m conjugate)
    20-25 mCi 99m Tc-EC20 administered IV 1-2 hours prior to imaging
    Other Names:
    • Folic acid-technetium 99m conjugate
    • FolateScan

Primary Outcome Measures :
  1. Maximum tolerated dose (MTD) [ Time Frame: Dose escalation to the highest dose that can be safely administered to produce acceptable, manageable and reversible toxicity in no more than 0 or 1 of 6 patients ]

Secondary Outcome Measures :
  1. Pharmacokinetic and pharmacodynamic parameters [ Time Frame: Obtained during the first cycle of therapy on Days 1 and 3 ]
  2. Anti-tumor activity [ Time Frame: Initial dose of study therapy to disease progression ]
  3. Uptake of 99mTc-Ec20 in tumors and normal tissues [ Time Frame: 1-2 hours post-administration of 99mTc-EC20 ]
  4. Safety and tolerability [ Time Frame: Initiation of study therapy through 30 day post last dose of study therapy ]

  • Evidence of symptomatic brain metastases
  • Receiving concomitant anticancer therapy (excluding supportive care)
  • Requires palliative radiotherapy at time of study entry
  • Unable to tolerate conditions for radionuclide imaging
  • Administration of another radiopharmaceutical that would interfere with assessment of 99mTc-EC20
